There is a basic explanation in the 2970 command reference.
Cisco - 2970 Command Reference - show dtp -

Hi Roy,
Until your post, I had never heard of the show dtp command and there were a
few times this command would have been very useful to know about.
I looked it up in the 3550 Command Reference and it's not there.
But, a quick check on a 3550 proves that this command does, indeed, exist.
Did you just happen upon this command by doing a show ? or did you learn
about this command another way?
I also see that an interface can be specified with this command but I
couldn't make much sense of much of the output. If this command is
documented somewhere, could you post a link?
TIA, Tim

Subject: disable dtp globally?
Hi,
I'm trying to disable DTP from running on my switches completely. I
have run switchport nonegotiate, but still get this under show dtp:
Global DTP information
Sending DTP Hello packets every 30 seconds
Dynamic Trunk timeout is 300 seconds
24 interfaces using DTP
Looks like its still enabled globally. I've even run switchport host,
same difference...
However, on the other side of my trunk links I don't see any DTP
packets, so it looks like its not running, at least on that link.
Debug DTP doesn't produce any hello packets every 30 seconds. Looks
like the message above it plain wrong?
Thanks again
Roy
